Question: are you planing on upgrading the rearend. That 261 will be "pulling on the bit" with the original rearend. There are a couple (maybe more) of rears that would allow a drum to disc conversion. That would be GM 10 and 12 bolts. With that conversion you can buy 2002 GM disc brakes that will bolt on.
I bought the CPP dual master cylinder and booster and am very happy with it.
